Example for /block/sda:
SUBSYSTEMS="scsi", ENV{COMMENT}="$attr{driver}"
sets COMMENT=sd
SUBSYSTEMS="pci", ENV{COMMENT}="$attr{driver}"
sets COMMENT=ata_piix

devices
This scheme is more consistent and makes it obvious if a match happens
against the event device only, or the full chain of parent devices.
The old key names are now:
BUS -> SUBSYSTEMS
ID -> KERNELS
SYSFS -> ATTRS
DRIVER -> DRIVERS
Match keys for the event device:
KERNEL
SUBSYSTEM
ATTR
DRIVER (in a future release, for now the same as DRIVERS)
Match keys for all devices along the parent device chain:
KERNELS
SUBSYSTEMS
ATTRS
DRIVERS
ID, BUS, SYSFS are no longer mentioned in the man page but still work.
DRIVER must be converted to DRIVERS to match the new scheme. For now,
an error is logged, if DRIVER is used. In a future release, the DRIVER
key behaviour will change.

Consecutive "add" events will not remove and recreate the same symlinks
anymore. No longer valid links, like after changing a filesystem label,
will still be removed.

We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

All udev state is kept in /$udev_root/.udev/ now. No option to
configure that anymore, it will always be there.

No device node or symlink can have other characters as plain
readable ascii or valid utf8. The /dev/disk/by-label/* symlinks
can no longer contain weird stuff read from untrusted sources.

This can be uses to export stuff to the event environment or
to carry a state from one rule to another, like enabling/disabling
later rules conditionally.

From: Bill Nottingham <notting@redhat.com>
Changed reading of firmware blob to mmap and let firmware_helper
follow the setting of the log level with UDEV_LOG.

This will allow us to have whole blocks of rules to skip
conditionally. The following section creates the node "yes":
GOTO="TEST"
NAME="no"
NAME="no2", LABEL="NO"
NAME="yes", LABEL="TEST"
NAME="no3"

This allows to source-in a file into the udev environment to have
the defined keys available for later processing by udev itself or
the forked helper programs.

All the rule files can be compiled into a single file,
which can be mapped into the udev process to avoid parsing
the rules with every event.

Former values are cleared if SYMLINK=<value> is used. To add a value
SYMLINK+=<value> is now needed.

Modern rules are expected to call notification and postprocessing with
the RUN key. For compatibility the current behavior can be emulated
with an external helper.

The use of KEY:=<value> will make the key unchangeable by later rules.
